4 Claims. (Cl. 37-42i Our invention relates to snow plow attachends oi'which are received in socket members 30 ments. It relates moreparticularly to such atand t2 carried by the forward ends of rods 34tachrnents by means of which a blade may be and 36 respectively. Theserods at first converge attached in front of a tractor to be pushed alongtoward each o ther .and then continue rearwardly li thereby and deliversnow to the side. One object to form portions parallel to each other asshown ci the invention is to provide shock absorbing in Fig. 2, the rearends being turned upwardly as means between the blade and the tractor inorder indicated at @il in Fig. l.

At the front oi the to prevent undue strains in case the blade strikesparallel portions of the rods 34 and it, posts 4l] an obstruction.Another object is toprovide runextend up vertically and carry plateau?provided W ners for supporting the blade from the ground. with holes Mfor bolting to flanges on the lower l Another object is to provide meansfor adjusting end of the casing it. The rods 34 and' 36 near the bladeup and down to meet various conditions their forward ends are connectedby a rod 4t. ot surfaces to be cleaned fromsnow.

jects and advantages will be best understood from As shown in Fig. 3 aplate 'it of hard or wear the following description of a specificembodiresisting metal is welded to the lower portion of ment in which,

Welded to the from the tractor. runner members 'l2 and to the blade is aright Fig. 3 is a view in vertical` section on the line angular striplil which has openings cut therein l-t of Fig. 2 and on en enlargedscale. to correspond with the spaces between the pairs Fig. ci is a Viewin vertical section on the line of pieces it.

ii-t of Fig. 3.

Welded to the strip 'M across the 3 openings thus provided arepins 'itwhich constiin Fig. l, the device is shown attached tothe tute bearingsfor eyes 'i3 formed on the lower ends iront of a garden tractor mountedon two wheels of auxiliary runner members lill.

one of which is designated by the numeral ill, 40 these wheels beingconnected by an axle i2 which supports a frame carrying a motor casing'i4, a differential casing I5, a transmission casing i6 and rearwardlyprojecting handles, one of which is designated by the numeral i8. Bymeans of rocked upon the axle i2.

The members blade 2n which as Shown in Figs. 1 and 2 com 20is supportedon the ground by the runner meinssts of a blade which is inclined inorder to throw bers 12' However by pushing down on the rods snow to theside of the tractor when employed u and then Securing them by the SetScrews 83 t() push the snow plow. TWO soket members the blade 2 Will beadjusted t0 2, higher pOSitOIl and 24 are secured to the rear of theblade 20 above the around due t0 the fact that the toggle near the lowerportion thereof as by welding. joints are moved downwardly from theirstraight These socket members receive the forward ends position. Thismovement of the blade is perof coiled springs 26 and 28 respectively,the rear mitted because the blade and its connections with Attached bypivots t2 to the upper ends of the members 88 are rods 34 which'passthrough openings formed in lugs 88 secured to the rear face of theblade. The rods Bd are held in adjustable position by set screws 83 asshown in Fig. 1. and the rods 84 in effect constitute toggle 45 thesehandles, the frame of the tractor may be joints near each of the twoends of the blade 2o. 4

Our tractor attachment includes a snow plow In the position Shown inFigs 1 and 3 the blade the tractor are capable of rocking movementaround the axle I 2.

The operation and advantages of our invention will be readily understoodin connection with the foregoing description and the accompanyingdrawings. 'I'he connections carried by the blade 2l are so constructedand arranged that the blade may be quickly attached in front of atractor such as a garden tractor to be pushed along by the tractor withside delivery of snow by the blade. 'Ihe tractor is easily manipulatedand controlled by the operator who in the embodiment shown walks behindand grasps the handles by means of which he may guidethe device with ahigh degree of precision. Upon bearing down upon the handles, the blade20 will be lifted in case it is desired to clear it from obstructions.'I'he blade may be lifted to a considerable extent and with the rear endportions of the connections then resting upon the ground. In case theblade strikes an obstruction, the springs 26 and 28 serve as shockabsorbers to prevent undue strain, the pivotal attachment of the rods 66and 68 permitting backward movement of the blade. In order to meetvarious conditions of the surfaces to be cleaned from snow, the blademay be adjusted up and down, the runner members 'I2 or 80 in all casesserving as a support for the blade.

We claim:

l. In a device of the character described, the combination of a blade,means for attaching said blade to the front of a tractor to operate infront thereof, pairs of spaced runners secured to the lower portion ofsaid blade, pivot pins secured across the spaces of said pairs ofrunne'rs respectively, auxiliary runners pivoted at their lower endsupon said pins, rods pivoted to upper ends of said auxiliary runners,and clamping members attached to the rear face of said blade forclamping said rods in adjusted position whereby said auxiliary runnersmay be raised and lowered.

2. In a device of the character described, the combination of a blade,means for attaching said blade to a tractor to operate in front thereof,said attaching means providing for rocking up and down movement of saidblade, pairs of spaced runners secured to the lower portion of saidblade, pivot pins secured across the spaces of said pairs of runnersrespectively, auxiliary runners pivoted at their lower ends upon saidpins, rods pivoted to the upper ends of said rods. and clamping membersattached to the rear face of said blade for clamping said rods inadjusted position, said rods and auxiliary runners when pusheddownwardly with said clamping members released serving to rock saidblade upwardly.

3. In combination with a tractor having a motor casing and adifferential casing, a snow plow attachment comprising a blade, a pairof rods extending from the rear of said blade near the lower portionthereof, posts extending upwardly from intermediate portions of saidrods, plates carried by the upper ends of said posts and adapted to besecured to the motor casing, a rod extending rearwardly from said posts,a plate carried by the rear end of said rod adapted to be secured to thedifferential casing. posts connecting said plate with the rear portionsof said pair of rods respectively, and rods pivotally attached at theirforward ends to the upper portion of said blade and attached to saidposts at their rear ends.

4. In combination with a tractor having a motor casing and adifferential casing, a snow plow attachment comprising a blade, a pairof rods extending from the rear of said blade near the lower portionthereof, posts extending upwardly from intermediate portions of saidrods, plates carried by the upper ends of said posts and adapted to besecured to the motor casing, a rod extending rearwardly from said posts,a plate carried by the rear end of said rod adapted to be secured to thedifferential casing, posts connecting said plate with the rear portionsof said pair of rods respectively, rods pivotally attached at theirforward ends to the upper portion of said blade and attached to saidposts at their rear ends, and a handle device extending rearwardly fromthe tractor by means of lwhich said blade may be given rocking movementaround an axle of the tractor.
